Descaling and expansion

- Jun 12, 2018-

Put the empty kettle on the stove to burn dry scale water, when burned to the bottom of the pot with a crack or burned to the bottom of the pot "bang" rang, the pot removed, quickly injected cold water, or with a cloth wrapped on the handle and spout, hands hold, will be a dry kettle quickly sitting in cold waters (do not let water into the pot).

Repeat 2 to 3 times, pot bottom scale will fall off due to thermal expansion and contraction.
